Interesting water behaviour x3

FX3OK · 03-26-2012, 10:07 PM

Not sure if its just me or this is not interesting at all... but during freeway drive in heavy rainstorm.. i noticed water accumulation on driver side window and virtually zero accumulation on passenger side. On the driver side, the water seemed to be trapped by a "vortex" and kept clinging to window. Has anyone else noticed this?

It's likely the rain was not coming from exactly head-on due to wind.

I assume you had wipers on?

Check how they work and where they push water and you might understand?

Though I have to say MY 2012 pushed driver side window excess water to upper part of the window and the water ran like a river towards back.

Just use "AquaPeal" or "RainX" and no more problems. And past a certain speed we didn't even need the windshield wipers.

(I have Aquapeal on windshield and RainX on other windows and lights)

It's the behavior of the wipers, which wipes the water to the driver side always...this is normal.

Is this your first car? hehe

Every car I've ever owned has done this to some extent (10+ cars/trucks)

I noticed this phenomenon as well when we were driving back from Spartanburg. I think when a thing is new all of the peculiarities seem so novel. Thought it was a design flaw at first.

Big fan of RainX amazing stuff

It certainly suggests significant drag likely produced by the side mirrors. Enough wind swirling to cause water to be trapped to the window. Hmmm oh well, no biggie but you would think water to be pushed away instead of "clinging"

Not a fan of Rain-X. Once applied, impossible to remove. Unless you keep topping it up you get awful wiper judder and noise. So yes, works well when recently applied. But my preference is for a clean glass screen that wipes normally. I even take care not to use the same chamois on glass that I do on bodywork - just to avoid transferring silicon-based compounds to the glass that I wont be able to shift. Ever. (yes, clear OCD trendencies..

). Going fast without the need for wipers at all is a one-time lo-thrill event. Why not just turn on the wipers?

Remember: you cant change you mind on this one! Be Sure before you try.

I noticed exactly the same thing last weekend when motorway driving in pouring rain for the first time. Not something I ever noticed in my previous LR Freelander 2
